cjtimeshares is my favorite when it comes to ebay sellers and Ive worked with 5 of them over the last year
They make mistakes, and there is no excuse for that, but they dont make excuses..they fix the mistakes
If you have a problem with one of their listings, call them..their phone number is right in their ads
If you are going to avoid timeshare sellers on ebay because of "mistakes" like the ones you mention....you better stay away from ebay altogether.....this ispart of the price you pay for the price you pay...Remember what Sergeant Phil Esterhaus used to say: "Hey, let's be careful out there"
in the interest of full disclosure I called cj yesterday. to make a deal on one of their ebay offerings...since there were no bidders they could accept my offer, which they did, they pulled the auction. I paid them and they made 3 reservations for me today...I like these guys
